Luke 8:18

This verse is a warming to all who hear the Word of God.  Previously Jesus described four different groups of people who heard God's Word and how they responded to it.  Here Jesus is warning those who hear it and pretend to accept it.  Jesus is telling those who hear and accept that in the end, they will gain even more; everlasting life with Him!  However, He is telling those that hear it and proclaim to be Christians but have never asked Jesus into their hearts that even what they think they have (Christianity) will be taken away with the words, "I never knew you."
